Hey Beemer fans, I'm after a quick indication of whether this is a simple fix, or a mechanic job - wasn't sure whether to devote a whole thread to it.
The car is a 1989 BMW E30 320i coupe, more than 250k on the clock.
I'm finding that after not driving the car for a fair time (1-2 weeks) while having it parked outside, when I do start it I'm getting a lot of hesitation, rough idling and even idling off. After persisting through the stuttering and frankly scary intersection close calls, it will eventually come right after warming up and will be fine as long as I start and give it a good run every few days.
Am I wrong to be suspecting some kind of moisture leak, or similar problem within the fuel system? It gets pretty wet here in Welly, and the rainy days seem to choke it up when it gets left outside. I've noticed the boot surrounding the fuel tank inlet is perished and has small holes, could water be getting into the fuel through there?
I initially thought it may have been the pod I put in sucking in moisture somehow, and so have gone back to factory with an aftermarket flat panel but the problem persists.
Like I said, just looking for a rough indication on whether to take the old girl down to JK Southern for some care, or whether this is common in older E30s. I should also add it got an elite service from Pit Stop less than a month ago, so fluids etc should be sweet.
Thanks in advance, sorry if this has been covered, if so please point me in the right direction.
